Abstract (en)

[origin: DE19843132A1] To apply a fluid to the surface of a moving yarn, the yarn is in contact with a powered rotating roller which carries a dosed volume of the fluid on its surface. The roller surface is coated with the dosed fluid through a number of capillaries in the roller mantle, forming pore openings in the mantle surface. In an Independent claim a rotating roller mantle (7) has a number of radial capillaries forming pore openings (8) distributed over the mantle surface (5). The capillaries are connected to the fluid feed (9). Preferred Features: The fluid is fed to the capillaries within the roller. The fluid moves to the roller mantle surface, through the pores, to form an even fluid film over the roller mantle surface. The capillaries are formed in a cuff, forming a mantle round the roller. The cuff is of a sintered material. The yarn passes partially round the roller mantle, or its path forms a number of loops round the roller mantle with its surface fluid film. The cuff (10) is turned up over the roller mantle, containing the capillaries and the saturated surface where the yarn (1) travels. The pore openings of the capillaries are distributed evenly over the whole surface of the roller mantle and cuff, or the pore openings are contained in an even pattern within a number of parallel surfaces around the mantle and cuff, each with a track to guide the yarn. The fluid feed is connected to a number of radial and/or axial grooves in the mantle surface, covered by the cuff of sintered material. The capillaries have a diameter of 10-1000 mu m.
